FCC Application for Krohne America, Inc. •FCC ID: JH5BM702 • Report No. EA0897-1 ______________________________________________________________________________ 11-Oct-00 Equivalent Radiated Power Conducted measurements of the transmitter output were not possible, since the horn antenna is permanently affixed. Therefore field strength measurements with a horn antenna were done instead. The following is the calculation of the limit in field strength based on the limit in power.
